Description
Technical field
The utility model relates to the technical field of low-pressure mercury discharge lamp, particularly relates to a kind of low-pressure mercury discharge lamp stoping displacement after mercury alloy melted by heating.
Background technology
In the middle of the gaseous discharge lamp adopting mercury alloy, the tube wall temperature of some discharge lamp is very high (being greater than 80 DEG C), cause alloy molten in the discharge lamp with mercury alloy, the mercury alloy of melting easily flows, when fluorescent tube is vertical or slant setting, or mercury alloy is when being in upper ends, alloy easily flows into other positions of fluorescent tube, the temperature of mercury alloy is caused to change, and then cause mercury alloy performance to change, cause fluorescent tube parameter to change a lot simultaneously, also alloy may be caused to flow on filament or near filament, cause open filament, also alloy may be caused to evaporate, fluorescent tube photoelectric parameter is caused to change, the bad phenomenon such as negative electrode blackout, long-standing problem lamp industry.
At present in the fluorescent tube of the discharge lamp of the solid mercury of band is produced, generally place mercury alloy in the non-positive column that temperature is lower, as being placed on the blast pipe place of fluorescent tube or being placed in fluorescent tube clamping plate, because this region amalgam temperature exists deviation, the photoelectric parameter consistency of lamp, poor stability.Also the manufacturer that has adopts at fluorescent tube positive column quartz tube wall outwardly, and mercury alloy is laid in the mode in fluorescent tube, but this product can only in fluorescent tube level and amalgam work in the position of fluorescent tube lower end, fluorescent tube service condition is extremely restricted.
Utility model content
The purpose of this utility model is to propose a kind of low-pressure mercury discharge lamp stoping displacement after mercury alloy melted by heating, it can light use in specific direction with under vibration condition, make mercury alloy that displacement of flowing all can not occur in lamp, photoelectric parameter deterioration can not be caused, also the problems such as negative electrode blackout can not be caused, consistency and the stability of the working temperature of the mercury alloy of every discharge lamp can be ensured simultaneously, thus be conducive to consistency and the stability of lamp running parameter, extend the useful life of discharge lamp.
For reaching this object, the utility model by the following technical solutions:
Stop a low-pressure mercury discharge lamp for displacement after mercury alloy melted by heating, it includes fluorescent tube and is arranged on the electrode of this lamp tube end, and is placed in the mercury alloy of this fluorescent tube inside, discharging chamber and blast pipe; The electric discharge positive column inwall of described fluorescent tube is provided with container cavity, described mercury alloy is positioned in described container cavity, and described container cavity is provided with through hole, the above-mentioned through hole be provided with, make discharge cavity and container cavity conducting, when energising is lighted, solid-state mercury alloy is heated, and the mercury vapour of formation enters in discharge cavity by through hole, light light fixture, meanwhile, because there is the restriction of container cavity, the mercury alloy in it can not because being subjected to displacement after melted by heating.
Preferably, in above-mentioned low-pressure mercury discharge lamp, the tapping of described through hole does not contact with described mercury alloy.Like this, low-pressure discharge lamp in use, melting after mercury alloy is heated, because it does not contact with the through hole on container cavity, therefore container cavity can not be flowed out, and fluorescent tube can in a certain direction along certain angle rotate (with fluorescent tube away from through hole end for axle, be rotated counterclockwise), only need ensure that after being heated, the mercury alloy of melting does not contact with through hole on container cavity in use, therefore the more traditional low-pressure discharge lamp of fixed position that needs of this low-pressure mercury discharge lamp tool has application space widely.
The shape of usual through hole is circular, rectangle, and square is oval, rhombus, the combination of polygon or above-mentioned shape.Operate for convenience and guarantee that having enough mercury vapour to pass through hole rapidly smoothly and enter discharging chamber in mercury alloy discharges, usual via area>=2 ㎜
2.In order to avoid flowing out container cavity when fluorescent tube works in the wide-angle situation such as vertical, the area of through hole should be less than or equal to the half of mercury alloy tiling area, and the minimum range of through hole and mercury alloy should be more than or equal to 3 millimeters simultaneously.
Further illustrate, the material that described container cavity adopts does not react with described mercury alloy, avoids causing mercury alloy composition to change on the one hand, thus causes its performance to change, and avoids it to pollute work atmosphere in mercury alloy and fluorescent tube on the other hand.The coefficient of expansion of the material of usual container cavity should adopt the close of material with fluorescent tube, avoids causing fluorescent tube to break because the coefficient of expansion is inconsistent, preferably adopts same material; More excellent, described fluorescent tube is made up of quartz glass.
Further illustrate, described mercury alloy and container cavity inwall attach fixing.Described through hole is set in container cavity and is not attached fixing position by mercury alloy.
Further illustrate, further illustrate, described container cavity is burn at the inwall of described fluorescent tube to melt connection glass hollow structural member.Glass hollow structural member can be enclosed construction, also can be semi-closed structure.Usually adopt closed structure when fluorescent tube is horizontally lighted, prevent the mercury alloy of melting from flowing out container cavity and be subjected to displacement.Then can adopt semi-closed structure during the vertical burning-point of fluorescent tube, only need guarantee that the mercury alloy of melting does not flow out container cavity and is subjected to displacement.
Illustrate further, described container cavity is the combination of cylindric or more the shape that cylindric, rectangular-shaped, spherical, one end of leaving certain gaps uncovered by the economic plan is closed.
The size of container cavity and shape should be consistent, and the fixed position of container cavity in fluorescent tube also should be consistent, mercury alloy also should be consistent in the position of container cavity, consistency and the stability of the working temperature of mercury alloy can be ensured like this, thus be conducive to consistency and the stability of lamp parameter; Container cavity is arranged at the fluorescent tube positive column of discharge stability for this reason.
The utility model is according to foregoing, a kind of novel low-pressure mercury discharge lamp is proposed, above-mentioned mercury discharge lamp is because being provided with the fixing container cavity of mercury alloy, can ensure that the steam of above-mentioned mercury alloy passes from described through hole smoothly and enter discharging chamber electric discharge, also can stop that the mercury alloy of molten state is subjected to displacement and flows into above-mentioned fluorescent tube simultaneously, the position of mercury alloy is caused to offset with the position designing setting before, in serious even inflow lamp, cause the optimum temperature range of mercury alloy work to change and cause mercury vapor pressure change in lamp, cause the deterioration of fluorescent tube photoelectric parameter, thus ensure that fluorescent tube parameter stability unanimously and extend useful life of described discharge lamp.
